In the article, “Partial Anomalous Left Pulmonary Artery,” by Collins et al that appeared in the May 5, 2009, issue of the journal (Circulation. 2009;119:2405–2407), the authors would like to acknowledge an oversight. It was incorrectly stated that only 2 cases of partial anomalous left pulmonary artery from the right pulmonary artery have been reported. In fact, there have been at least 3 cases. The article should thus have cited the following report:
Ge S, DeGroff CG, Knudson O, Strain J, Chan KC. Noninvasive assessment of pseudo-pulmonary artery sling by echocardiography and computerized tomography. Circulation. 2001;103:e115–e116.
Reference to this report has been added to the current online version of the article. The authors regret the error.
